CD143A-SR05~12 – Steering/TVS Diode Array Series
General Information
The CD143A-SR05 and CD143A-SR12 devices provides ESD, EFT
and surge protection for the external ports of portable electronic
devices such as cell phones, handheld electronics and personal
computers.

The ESD protection provided by the component enables a data
port to withstand a minimum ±± ꢀV Contact ꢁ ±15 ꢀV Air Discharge
per the ESD test method specified in IEC 61000-4-2. The device
measures 2.±0 mm x 1.20 mm and is available in a SOT-143
package intended to be mounted directly onto an FR4 printed
circuit board.
The Bourns® device will meet IEC 61000-4-2 (ESD), IEC 61000-4-4
(EFT) and IEC 61000-4-5 (Surge) requirements.

** Bourns follows the prevailing definition of “halogen free” in the industry. Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less;
(b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.
